macOS Bluetooth IO problem

[ericshape]

Hi!
I am trying to implement a course project which use the Wii's Remotes and the Wii's Balance Board based on the WiiC open source library. But, when I run it, its errors outputs show: "Unable to write over the output channel" and "Failed to create IOKit notification…". Do you have any experience to meet this errors? How can I deal with this problems?
Thanks!
Ji

Those errors look like strings put in by whoever wrote your course project materials rather than generic ones. Unless we have access to the source code we can't really help.
